Letters Patent No. 65,322, dated IVIag/ 28, 186i'.

IMPROVEMENT IN LAMI??BURNERSl TO ALL WHOM IT MAY GONOERN:

Beit known that I, JOHN B. VORTHAM, of Huntsville, in the State of Alabama, have invented a certain new and useful Improvement in Lamps; and I do hereby declare that the following is a full, clear, and exact description of-the same, reference being had to the accompanying drawings, and to the letters and marks thereon, which said drawings form part of this specication, and show my improvement as applied to a lamp, and in detail- Figure 1 thereof being a View in elevation of a burner attached to the upper partv of the lamp.

Figure 2 being a. viewofl an inner part of the burner.

Figure 3 being a View of the wicktube and plate; and

Figure 4, a view of the Ventilating collar or cylinder.

In each of these figures like parts are indicated by like letters.

My invention is more particularly intended to be used on lamps for burning coal oil, but may be used in lamps of any construction and designed for any other oil or illuminating uids. My `improvement will render any lamp safe and non-explosive, and will afford a clear and good flame, and free and fully supply of air thereto.

The wick-tube a is firmly fixed to the plate b, so that its joint is air-tight. This may be produced by having the two pieces fitting closely together and then burnished, or, in case the tube is round, by nely-cnt screw-v threads. Upon the edge of the plate are teeth, which, Ias the Ventilating collar or cylinder c is moved up or down, fit into the slots of that cylinder, and free them from any soot or other matter that usually tends to lill up or clog'the ventilator. This cylinder c surrounds the body part ol of the burner, and may be moved upand down thereon, so that the lamp may be lit without elevating the cap e. A coiled spring, f, surrounds the body .partd, the upper end of which is affixed to the Abody at z, while the lower end x is affixed tothe lower andV part oi' the Ventilating cylinder c. The fitting of the lower end of this spring tothe cylinder c is indicated by the'dotted lines in iig. 4. The tendency of this spring is to elevate the cylinderc, and to keep its upper edge in contact with the cap e. Other means than this spring may be used in some cases, and on some lamps only friction-plates or springs would answer. To the body part cZ are affixed plates, the one, g, being'for the hinge of the cap, and the other, 71 for the catch. A small plate, z', on the cap, whenthe cap is thrown fully up, as is represented by the red lines in ig. I, will fit into the space between the platej on the cylinder c and the sides of the cylinder, and thus hold the cap up. As this burner will be air-tight, holes k through the body part, as indicated in fig. 2, will allow air to pass into the lamp as the oil is consumed, and hence there can be no chance for explosion. When the cylinder c is pressed down, the plate vb can easily be brushed olf, and the interior of the burner readily be cleaned. The different positions of the capand the cylinder and the Aparts of the burner are fully indicated by the black lines in thc one case, and -the red lines in the other case of fig. l. In globe or`stationary lamps thev burner can be readily lit without disturbing the cap or chimney or globe.

What I claim as my invention, and desire to secure by Letters Patent, is v 1. The ventilating collar or cylinder c, constructed and operated and for the purposes substantially as herein recited.

2. In combination with the cylinder c, the toothed edge of the plate b or its equivalent.

3. The plates z' and j for holding the cap open, as described.
